Nature's Way Alive! Vitamin C Powder 120 g Vitamin C is more than just ascorbic acid. It's part of a total complex that also includes bioflavonoids and co-factors known to aid its absorption into the body. Whole food source vitamin C is also naturally buffered so it's less acidic and gentler on the stomach. Alive! Vitamin C is complete vitamin C  the way Mother Nature intended. Unlike other dietary supplements that use isolated ascorbic acid or cultured bacteria as their sources of vitamin C, Alive! Vitamin C derives its entire vitamin C content naturally from four of Mother Nature's most potent organic sources: organic acerola berries, organic goji berries, organic kiwi fruit and organic amla fruit.
